Equivalent Circuit Representation and Thermodynamic Limitations of Non-Adiabatic Spin-Transfer Torque effect
Wataru Koshibae
We present an equivalent circuit representation of the Thiele equation for the current-driven domain walls. We show that the non-adiabatic spin-transfer torque (β-term) cannot be r…
Visualizing Microwave-Driven Dynamics of Antiskyrmions and Surface Skyrmions
Zhuolin Li, Daisuke Nakamura, Spencer Reisbick +9
Microwaves provide coherent access to low-energy excitations and serve as effective probes of high-frequency spin dynamics in quantum and magnetic systems. For topological spin tex…

Reconsidering the nonlinear emergent inductance: time-varying Joule heating and its impact on the AC electrical response
Soju Furuta, Wataru Koshibae, Keisuke Matsuura +5
A nonlinearly enhanced electrical reactance, , under a large AC current has been measured to explore emergent inductors, which constitute a new class of inductors based on t…
